### StringUtils

    public StringUtils()

Method Detail

### splitAndTrim

    public static String[] splitAndTrim(String string,
                                        String delim)

  Like `StringUtils.split(String, String)`, but additionally trims whitespace from the result tokens.

### hexStringToByteArray

    public static byte[] hexStringToByteArray(String hex)

  Convert a hexadecimal string into its byte representation.

  Parameters:
    `hex` - The hexadecimal string.
  Returns:
    The converted bytes or `null` if the hex String is null.

### repeat

    public static String repeat(char c,
                                int len)

  Like `StringUtils.repeat(String, int)` but with a single character as argument.

### toHexString

    public static String toHexString(byte[] bytes)

  See Also:
    `toHexString(byte[])`

### toHexString

    public static String toHexString(byte[] bytes,
                                     boolean uppercase)

  Convert a byte array to a hexadecimal string.

  Parameters:
    `bytes` - The bytes to format.
    `uppercase` - When `true` creates uppercase hex characters instead of lowercase (the default).
  Returns:
    A hexadecimal representation of the specified bytes.
